Resumo

An extensive search for the linear C2N radical towards the circumstellar envelope IRC+10216 has been performed. Eight frequency bands of the rotational transitions J = 7/2–5/2 up to 13/2–11/2 and 17/2–15/2 up to 23/2–21/2 of the C2N molecule including their λ-doubling components have been probed, using the IRAM 30 m telescope at Pico Veleta, Spain. However, there is no evidence for the existence of the C2N radical towards IRC+10216. Instead, a new upper limit cm-2 for the column density of C2N was estimated. Additionally, at least ten yet unidentified lines have been found.
